"What the show is made up of is a lot of later Beatles' material that the band never performed live, so as well as John Lennon, Paul McCartney, George Harrison and Ringo Starr, we are looking for a fifth person who can play the keyboards. I'm hoping to be inundated with Liverpudlians who can play and sing, and if they look a little bit like the Beatles then that's helpful - but what we're really looking for is high-quality musicians," he added.

Those interested will have the chance to audition for the show in London's West End by heading to the famous Cavern Club in Liverpool on May 1. There will be another casting call at London's Gielgud Theatre on May 8.
